+Purpose: define the public-use boundary for Mullusi documentation source.
+Governance scope: public documentation, examples, claims, attribution, and private-information exclusion.
+Dependencies: docs.mullusi.com, mullusi/mullusi-site, Mullusi ops authority, and repository validation scripts.
+Invariants: public documentation contains no secrets, no private roadmap commitments, and no unsupported production guarantees.
+-->
+
+# Publication Policy
+
+This repository is publicly visible because it is the source for
+`docs.mullusi.com`. Public visibility is not a blanket release of private
+Mullusi operational material.
+
+## Public Boundary
+
+Allowed public content:
+
+1. Architecture contracts that are intended for developer understanding.
+2. Public API descriptions that are labeled by maturity.
+3. Tutorials that can be reproduced from public source.
+4. Governance rules that explain verification, traceability, and constraints.
+5. Mfidel documentation that preserves fidel atomicity and avoids decomposition models.
+
+Blocked public content:
+
+1. Production secrets, credentials, private keys, cookies, or provider tokens.
+2. Private roadmap details that are not approved for public release.
+3. Internal cost, account, or vendor-control details.
+4. Unsupported production guarantees.
+5. Ethiopian script processing that decomposes fidel into root-letter or Unicode-normalized units.
+
+## Claim Discipline
+
+Every public technical claim must be one of:
+
+| Claim type | Requirement |
+| --- | --- |
+| Implemented | Linkable to source, test, workflow, or live surface |
+| Draft | Marked as draft or unstable |
+| Roadmap | Marked as planned and not production-ready |
+| Research | Framed as research, not a deployed guarantee |
+
+## Reuse Boundary
+
+Code snippets that appear in tutorials are intended for reader execution in the
+documented context. Broader reuse, redistribution, or product incorporation is
+not granted by this policy alone. Add an explicit license file before making a
+broader reuse grant.
+
+## Verification
+
+Run before publishing documentation changes:
+
+```bash
+node --check assets/search.js
+node scripts/validate-docs.mjs
+```
+
+For launch-facing claims, also record the relevant ops verifier result.
